In the context of differential extraction, certain binary mixtures can be effectively separated into their individual components based on their solubility differences in various solvents. Here’s a breakdown of the options provided:
Options Analysis
- A. C₆H₅OH, C₆H₅COOH: These compounds can be separated because phenol (C₆H₅OH) is more soluble in organic solvents, while benzoic acid (C₆H₅COOH) can be extracted into an aqueous phase when neutralized.
- B. C₆H₅COOH, C₆H₅CH₂OH: This mixture can also be separated. Benzoic acid can be extracted into water, while benzyl alcohol (C₆H₅CH₂OH) remains in the organic layer.
- C. C₆H₅CH₂OH, C₆H₅OH: These two alcohols have similar properties, making them difficult to separate by differential extraction.
- D. C₆H₅CH₂OH, C₆H₅CH₂COOH: This mixture can be separated since the carboxylic acid (C₆H₅CH₂COOH) can be extracted into the aqueous phase, while the alcohol stays in the organic phase.
Correct Options
The mixtures that can be separated by differential extraction are:
- A. C₆H₅OH, C₆H₅COOH
- B. C₆H₅COOH, C₆H₅CH₂OH
- D. C₆H₅CH₂OH, C₆H₅CH₂COOH
In summary, options A, B, and D are suitable for separation through differential extraction, while option C is not effective for this method.
